MIPS: perf: More robustly probe for the presence of per-tc counters
The presence of per TC performance counters is now detected by
cpu-probe.c and indicated by MIPS_CPU_MT_PER_TC_PERF_COUNTERS in
cpu_data. Switch detection of the feature to use this new flag rather
than blindly testing the implementation specific config7 register with a
magic number.
